When printing from a web application like ParaSQL, the web browser has a lot of control over the final result.
ParaSQL can't override certain settings. This can be especially problematic with Chrome (esp v54.x).
Most web browsers scale the output of the web page. With IE11 and Firefox you can control this print scaling (down to the percentage in Firefox, in IE11 you can choose to Shrink to Fit or not). Chrome doesn't have any options in this area, and the way it scales can be a mystery.
For example, Chrome may change the print scaling, and therefore the width of the layout, depending upon the number of ROWS printed... making consistent size output near impossible.
Until (if?) Chrome ever gets around to providing decent print capability, we suggest you use Firefox so that you can control the scaling as needed.
